How to open the fob without breaking it, and which substitutions actually work. **Quick answer**: The 2018-2024 Toyota Camry key fob takes a CR2032 coin-cell battery, available at any pharmacy, hardware store, or online for a few dollars. ## Replacing the 2018-2024 Toyota Camry key fob battery - Pry the fob open gently at the seam with a small flathead screwdriver or a coin, working around the edge. Many fobs have a hidden release slot near the key ring or emergency-key blade. - Note the battery orientation (usually positive side up) before removing the old cell. - Avoid touching the new battery's faces with bare fingers; skin oils can shorten its life. - If the fob doesn't work after replacement, check that the battery is seated fully and the contacts weren't bent. Most vehicles do not need re-pairing after a battery change. ## Which Toyota Camry model years does this cover? These key fob battery specifications apply to every Toyota Camry built from 2018 through 2024, the XV70 (8th generation), mid-size sedan (tnga-k platform). Nothing in this specification changes between those model years. - [2018 Camry](https://whichcarparts.com/cars/toyota/camry/2018) - [2019 Camry](https://whichcarparts.com/cars/toyota/camry/2019) - [2020 Camry](https://whichcarparts.com/cars/toyota/camry/2020) - [2021 Camry](https://whichcarparts.com/cars/toyota/camry/2021) - [2022 Camry](https://whichcarparts.com/cars/toyota/camry/2022) - [2023 Camry](https://whichcarparts.com/cars/toyota/camry/2023) - [2024 Camry](https://whichcarparts.com/cars/toyota/camry/2024) ## What changed during the 2018-2024 Toyota Camry | Years | What changed | | --- | --- | | 2018 | Generation launch on TNGA platform; LED headlights standard on all trims | | 2020 | AWD became available on 4-cylinder trims; Android Auto added; TRD V6 trim introduced | | 2021 | Facelift: revised fascias and wheels, floating touchscreen, Toyota Safety Sense 2.5+; Hybrid XSE added | | 2023-2024 | Carryover years; final V6 Camrys | | 2024 | Carries over with minimal changes; the redesigned hybrid-only XV80 arrives for 2025 | ## 2018-2024 Toyota Camry key fob battery: common questions ### What battery does the 2018-2024 Toyota Camry key fob take? A single CR2032 coin cell. ### Can you use a CR2032 instead of a CR2025 in a 2018-2024 Toyota Camry key fob? This fob takes a CR2032, so start there. The two cells share a 20 mm diameter but differ in thickness, and the thicker one does not always seat in a housing built for the thinner. ### How do you open a 2018-2024 Toyota Camry key fob? Slide out the mechanical emergency key first, which usually releases a catch, then part the halves with a plastic pry tool or a coin wrapped in tape. A screwdriver will mark the case and can crack the seam. ## Sources - [Toyota technical data, Camry XV70 fluids & capacities (toyota-club.net)](https://toyota-club.net/files/techdata/ttx/camry_70u.htm) - [Toyota parts catalog, 87139-0E040 cabin air filter (parts.toyota.com)](https://parts.toyota.com/p/Toyota_2018_Camry/Cabin-Air-Filter/66836259/871390E040.html) - [Toyota parts, 17801-F0050 engine air filter fitment (Frontier Toyota)](https://parts.frontiertoyota.com/oem-parts/toyota-engine-air-filter-2-5l-a25afks-4-cylinder-3-5l-2grfks-v6-17801f0050) - [NHTSA recall 20V-012, Denso fuel pump](https://static.nhtsa.gov/odi/rcl/2020/RCLRPT-20V012-4479.PDF) - [NHTSA recall 21V-890, brake vacuum pump](https://static.nhtsa.gov/odi/rcl/2021/RCMN-21V890-8677.pdf) - [NHTSA recall 20V-064, engine block porosity](https://static.nhtsa.gov/odi/rcl/2020/RCAK-20V064-2632.pdf) - [TirePressure.org, 2018 Toyota Camry placard pressures](https://tirepressure.org/toyota/camry/2018) - [fueleconomy.gov, 2018 Camry / Camry Hybrid EPA ratings](https://www.fueleconomy.gov/feg/bymodel/2018_Toyota_camry.shtml) - [ToyotaNation, XV70 OEM battery H5/Group 47 discussion](https://www.toyotanation.com/threads/2018-camry-battery-size-dillema.1760261/) ## Other Toyota Camry generations - [2025 Toyota Camry key fob battery](https://whichcarparts.com/cars/toyota/camry/2025/key-fob-battery) - [2012-2017 Toyota Camry key fob battery](https://whichcarparts.com/cars/toyota/camry/2012-2017/key-fob-battery) Or [compare all generations](https://whichcarparts.com/cars/toyota/camry/key-fob-battery). ## More for the 2018-2024 Toyota Camry - [Oil & filter](https://whichcarparts.com/cars/toyota/camry/2018-2024/oil) - [Battery](https://whichcarparts.com/cars/toyota/camry/2018-2024/battery) - [Tires & wheels](https://whichcarparts.com/cars/toyota/camry/2018-2024/tires) - [Wiper blades](https://whichcarparts.com/cars/toyota/camry/2018-2024/wipers) - [Air & cabin filters](https://whichcarparts.com/cars/toyota/camry/2018-2024/filters) - [Bulbs](https://whichcarparts.com/cars/toyota/camry/2018-2024/bulbs) - [Brakes](https://whichcarparts.com/cars/toyota/camry/2018-2024/brakes) - [Fluids](https://whichcarparts.com/cars/toyota/camry/2018-2024/fluids) - [Service schedule](https://whichcarparts.com/cars/toyota/camry/2018-2024/service-schedule) - [Problems & reliability](https://whichcarparts.com/cars/toyota/camry/2018-2024/common-problems) - [Oil light reset](https://whichcarparts.com/cars/toyota/camry/2018-2024/oil-reset) - [Specs](https://whichcarparts.com/cars/toyota/camry/2018-2024/specs) Specifications vary with engine option, production date, and market.
